Import coil pipe 30 of the present invention has inlet end 32, and this inlet end 32 is connected on the outlet port 130 of steam gas conversion reactor 110 through rigid line.Import coil pipe 30 comprises the pipe section 34 that is rigidly connected, and this pipe section 34 that is rigidly connected generally can comprise inlet end 32 (and outlet port of steam gas conversion reactor 110) is connected to the straight section of needed pipeline on the end of coil portions 36 of import coil pipe 30 and any combination of bending section.The opposed end of coil portions 36 has outlet end 38, and this outlet end 38 is connected on the inlet ports 28 of WGS container 20.
Outlet coil pipe 60 of the present invention has inlet end 62, and this inlet end 62 is connected on the outlet port 50 of NG pre-heater 40, is used for receiving the reformate that leaves NG pre-heater 40.The inlet end 62 of outlet coil pipe 60 is connected on the end of coil portions 64.The opposed end of coil portions 64 is connected on the rigid conduit coupling part 66, and this rigid conduit coupling part 66 has outlet 68.The pipe section 66 that is rigidly connected generally can comprise any combination that outlet 68 is connected to the straight section and the bending section of needed rigid conduit on another element, this another element is pre-heater 120 in this case, and this pre-heater 120 was used for preheated air before air is used in steam gas conversion vessel 110.
The coil portions 36 of import coil pipe 30 is made by pipe or pipeline, and this pipe or pipeline are bent to form spiral coil.In an illustrated embodiment, the coil portions 36 of import coil pipe 30 is twined about four times around WGS container 20; Yet the coil portions 36 of import coil pipe 30 is optionally twined than the number of times of Duoing in an illustrated embodiment or few number of times around WGS container 20.Coil portions 36 forms a helical spring.
The coil portions 64 of outlet coil pipe 60 is made by pipe or pipeline, and this pipe or pipeline are bent to form spiral coil.In an illustrated embodiment, the coil portions 64 of outlet coil pipe 60 is twined five times around WGS container 20; Yet the coil portions 64 of outlet coil pipe 60 is optionally twined than the number of times of Duoing in an illustrated embodiment or few number of times around WGS container 20.Coil portions 64 forms a helical spring.
As appreciable among Fig. 2 A and the 2B, the distance that the inlet ports 28 of WGS container 20 is arranged on from the upper surface of pedestal 12 is d 1The height place, WGS container 20 is installed in this pedestal 12.In addition, to be arranged on the distance from the upper surface of pedestal 12 be d to the outlet port 24 of WGS container 20 2The height place.In the operating period of WGS container 20, WGS container 20 will be heated, and this will cause the prolongation along its axial length of the thermal expansion of WGS container 20 and WGS container 20.Thereby, apart from d 1And d 2Will from cold, non-operating state change to heat, mode of operation, thereby d 1 (mode of operation)＞d 1 (non-operating state), and d 2 (modes of operation)＞d 2 (non-behaviour Make state)
Except that the change in location of the inlet ports 28 of WGS container 20 and outlet port 24, for the port of the element that is connected with inlet ports 28 and outlet port 24, the thermal expansion owing to these elements also can change the position.The port 24 of WGS container 20 moves and can produce stress in pipeline connects with the relative position of the port of other element (WGS container 20 be connected by pipeline be interconnected on these other elements) with 28, this pipeline connect or port in can cause and lost efficacy or accelerate fatigue failure.And, if one or more ports of WGS container 20 are connected on the port of one or more other elements through connecting pipe, does not move (promptly the position of these one or more other elements, do not expand or shrink) and thereby remain on the place, fixed position, the position of the port of WGS container 20 is moved and will be produced stress in pipeline connects so, and this can cause inefficacy or accelerate fatigue failure in pipeline connection or port.
Based on experience or calculating, the relative position between the outlet port of the inlet ports 28 of WGS container 20, the element that is connected with this port moves, and can be determined between the non-operating state of WGS container 20 and this element and mode of operation.In case this relative position moves and is determined, then the coil portions 36 of import coil pipe 30 can be configured to, and the relative position that is absorbed between the outlet port of the inlet ports 28 of WGS container 20, the element that is connected with this port moves.
Similarly, the relative position between the inlet ports of the outlet port 24 of WGS container 20, the element that is connected with this port moves, and can be determined between the non-operating state of WGS container 20 and this element and mode of operation.And, in case moving, this relative position is determined, and the coil portions 64 that then exports coil pipe 60 can be configured to, and the relative position that is absorbed between the inlet ports of the outlet port 24 of WGS container 20, the element that is connected with this port moves.
In a preferred embodiment of the invention, coil portions 36 and 64 is configured to, and during the mode of operation of WGS container 20 and the element that is connected thereto, has low stress or does not have stress in import coil pipe 30 and outlet coil pipe 60.Thereby the helical spring that is formed by coil portions 36 and 64 during the mode of operation of WGS container 20 and the element that is connected thereto, is under unstressed, the non-compressed state.Yet, when WGS container 20 and the element that is connected thereto in cold, non-operating state following time, the thermal contraction of WGS container 20 and the element that is connected thereto will cause that the relative position between respective inlets and outlet port moves, and this will axially compress the helical spring that is formed by coil portions 36 and 64.Thereby under cold, non-operating state, the helical spring that is formed by coil portions 36 and 64 will be under the compressive state.
Fig. 4 A and 4B are illustrated under the compressive state and the figure of the coil pipe under non-compressed state, so that the explanation of how to construct coil portions 36 of the present invention and 64 is provided.Each coil portions can be configured to, and coil pipe is when having axial length d in the non-compressed state following time shown in Fig. 4 B 3, and when having axial length d in the compressive state following time shown in Fig. 4 A 4In case determine that with the element that is connected with them of outlet port 24 relative position moves for inlet ports 28, the position movement value that is used for inlet ports so all can be used as apart from d with each value of the position movement value that is used to export port 24 5, this is apart from d 5Be coil portions 36 and 64 respective distance that between the installation period under the non-operating state, should compress.Thereby during mode of operation, relative position moves and will make helical spring remove compression, thereby pipeline junction is under stress-free conditions.
Selectively, coil portions can be configured to, and spiral coil is in the compressed configuration under mode of operation, and is in during non-operating state in the non-compressed configuration.Further selectively, coil portions can be configured to, and spiral coil is not when being stretched in stress state following time and not by compression.Selectively, coil portions can be configured to, spiral coil under mode of operation by compression, under non-operating state, stretched, and be heated to from cold, non-operating state when system during time point heat, during mode of operation and when system during time point heat, when mode of operation is cooled to cold, non-operating state, be under the unstress state.Further selectively, coil portions can be configured to, spiral coil is stretched under mode of operation, under non-operating state by compression, and be heated to from cold, non-operating state when system during time point heat, during mode of operation and when system during time point heat, when mode of operation is cooled to cold, non-operating state, be under the unstress state.
Thereby, coil system of the present invention can be configured to expediently absorb stress reliably and not lose efficacy, can be configured to reduce to change the stress numerical that causes, and/or the person can be configured to provide unstressed mode of operation or unstressed non-operating state according to different needs by the thermal expansion in whole system.The import by considering the various elements that caused by thermal expansion in system and the relative position of outlet change, and coil system of the present invention can provide firm pipe-line system.If wish that then coil pipe (one or more) can be made, and is remaining between the time of shipment under the pre-stressed state under pre-stressed state, thereby pipe-line system is stressless under normal operating condition.For example, if determine that it will be 0.75 inch that relative position from cold state to hot mode of operation moves, thereby then coil pipe can be had 0.75 inch axial compression by prestress.
